Calling under pressure: short-finned pilot whales make social calls during deep foraging dives.
Toothed whales rely on sound to echolocate prey and communicate with conspecifics, but little is known about how extreme pressure affects pneumatic sound production in deep-diving species with a limited air supply. The short-finned pilot whale (Globicephala macrorhynchus) is a highly social species among the deep-diving toothed whales, in which individuals socialize at the surface but leave the...
متن کاملChanges in dive behavior during naval sonar exposure in killer whales, long-finned pilot whales, and sperm whales
Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), seven long-finned pilot whales (Globicephala melas), and four sperm whales (Physeter macrocephalus) was studied during controlled exposures to naval sonar [low frequency active...
متن کاملEffects of a morbillivirus epizootic on long-finned pilot whales Globicephala melas in Spanish Mediterranean waters
Long-finned pilot whales Globicephala melas are a commonly encountered species in the Mediterranean Sea. In 2006−2007, an outbreak of the dolphin morbillivirus in the Western Mediterranean resulted in increased mortality of this species. The aim of this study was to determine whether survival rates differed between clusters of Spanish Medi terranean pilot whales, and how the epizootic in fluenc...
متن کاملFatal Asphyxiation in Two Long-Finned Pilot Whales (Globicephala melas) Caused by Common Soles (Solea solea).
Long-finned pilot whales (Globicephala melas) are rare visitors to the southern North Sea, but recently two individual strandings occurred on the Dutch coast. Both animals shared the same, unusual cause of death: asphyxiation from a common sole (Solea solea) stuck in their nasal cavity. This is a rare cause of death in cetaceans. Whilst asphyxiation has been reported in smaller odontocetes, the...
متن کاملBag-of-calls analysis reveals group-specific vocal repertoire in long-finned pilot whales
This is the first description of group specific vocalizations of long-finned pilot whales. Sounds were recorded and analyzed from seven different social groups of long-finned pilot whales in the Vestfjord in northern Norway between November 2006 and August 2010. We analyzed the sound recordings by three different methods: First, we created a baseline data-set by doing a classical observer-based...
